+Git Strategy
+------------
+
+The repo adopts a simple git strategy where all contributions to the repo are made to the ``dev``
+branch (i.e. all Pull-Requests must use ``dev`` as the target branch). On a monthly cadence (decided
+and controlled by the SIG-ARCH-TEST members) the ``dev`` branch will be merged to the ``main`` to by
+the official maintainers of the repo. This will create an official release capturing all the 
+development over the month into a single release.
+
+To implement the above strategy successfully the following needs be followed:
+
+* Developers: All pull-requests from developers must target the ``dev`` branch and the PR must
+contain an entry in the CHANGELOG.md file under `[WIP-DEV]` section.
+* Maintainers: When a making a release the maintainers shall assign semantic version number by
+updating the CHANGELOG and the respective python files before raising a PR from the `dev` to `main`.

 Merge Request Guidelines
-----------------------------
+------------------------
 
 Before you submit a merge request, check that it meets these guidelines:
 
-1. The merge request should include tests.
+1. The merge request should include tests (if any).
 2. If the merge request adds functionality, the docs should be updated. 
-3. The merge request should work for Python 3.6, 3.7 and 3.8, and for PyPy. 
-   and make sure that the tests pass for all supported Python versions.
+3. The target branch must always be the `dev` branch.
+
+
+Versioning (only for maintainers)
+---------------------------------
+
+When issuing pull requests to the main branch (from dev), a version entry in the CHANGELOG.md is mandatory. The tool adheres to
+the [`Semantic Versioning`](https://semver.org/spec/v2.0.0.html) scheme. Following guidelines must
+be followed while assigning a new version number :
+
+- Patch-updates: all doc updates (like typos, more clarification,etc).
+- Minor-updates: Fixing bugs in current features, adding new features which do not break current
+  features or working. Adding new extensions.
+- Major-updates: Backward incompatible changes.
 
-Tips
-----
+Note: You can have either a patch or minor or major update.
+Note: In case of a conflict, the maintainers will decide the final version to be assigned.
 
-To run a subset of tests::
+To update the version of the python package for deployment you can use `bumpversion` (installed
+using ``pip install bumpversion``)::
 
-    $ pytest tests.test_riscv_ctg
+$ bumpversion --no-tag --config-file setup.cfg patch # last arg can be: major or minor or patch
 
+If you don't have bumpversion installed you can manually update the version in the following files:
 
-Deploying
----------
+- change the value of variable ``current_version`` in `./setup.cfg`
+- change the value of variable ``__version__`` in `./riscv_ctg/__init__.py`
 
-A reminder for the maintainers on how to deploy.
-Make sure all your changes are committed.
-Then run::
 
-$ bumpversion --no-tag --config-file setup.cfg patch  # possible: major / minor / patch
-$ git push origin name-of-your-branch
